4 Claims. (01. 108-7) This invention relates to roofing, and more particularly to shingles or covering uni-ts, pref-,

erably formed from bituminized fabrics or other compositions. v

Most of the asphaltic or prepared roofings are made up of a single layer of roofing felt saturated with bituminous ingredients of relatively soft consistency and surfaced on both sides with harder bituminous compositions. sheets are then divided into individual shingles or slabs, adapted to be laid in overlapping courses on a roof structure. The exposed butts or corners thereof have a tendency to curl and blow I up, thereby giving access to rain and snow.

This invention relates to shingle elements which are cut with oblique or inclined side edges so that they may be arranged in overlapping courses with the corners of the exposed butts secured to prevent curling or lifting. Where the shingle elements are cut in the form of slabs or strips, they may be marked off to simulate fur- 'ther sub-divided shingle elements.

This case is a division of application Serial No. 501,443, which issued into Patent No.- 1,729,212, September 14, 1929. I

Figure 9 is a plan view of another modified form of slab or strip in which a series of individual shingles are overlapped; and

Figure 10 is a plan view of a roof section showing the roof design formed by the roofing slabs These prepared overlapping courses with the butt ends 4 exposed Referring to the drawing, numeral 2 (Fig. 1)

designates a rogfing' unit cut from a sheet in the form of what is known in the trade as individual shingles. Rather than out the individual shingles in rectangular form as is ordinarily done, the sides 3 are inclined obliquely to the butt ends 4 and 5. A series of these units may be laid in to the weather or they may be inverted (Fig. 2)

and laid with butt ends 5 exposed.

Instead of being in the form of individual shingles the units may be in the form of slabs or strips 6 having a length double or more that of the width. One form of such slab or strip is illustrated in Figs. 3 and 4 wherein the body diverges into two wings 7 to provide a convexlike butt end 8 and a concave-like butt end9. The butt ends may be advantageously cut out (Fig. 5) at intervals 10 to provide a series of tabs 11 to simulate individual shingles.

The roofing units may be arranged in various ways to effect artistic roofing designs. In Figs. 6 and '7, I have illustrated suitable methods for laying the roofing units shown in Figs. 3 and 4. Onemethod (Fig. 6) for providing a waterproof layer with a minimum number of roofing units is to lay the units in courses with the ends of adjacent units overlapped and the exposed butt ends overlapping the top edges of the underlying courses. Adjacent units are irregularly staggered by having alternating units in each horizontal course oil-set from horizontal alignment and the ends of the units alternately overlapped. In carrying out this method of laying, the roofing units may be laid with either butt end exposed to the weather. The method of laying is the same, irrespective of which butt end is exposed to the weather.

In Figure '7 the roofing elements are alternately inverted vertically and horizontally to effect a different design and to provide a double layer roofing. The intermediate area 0 between areas a and 1) illustrates a method for arranging the roofing elements alternately inverted to efiect a diamond design with the exposed butt ends of the roofing units.

The modified forms in Figures 8-10 inclusive disclose other ways of marking the unitary butt ends to simulate individual roofing units. Oblique shingle strip 12 is formed with a unitary butt end 13 having sides 14 and 15 symmetrically inclined. The surface of the shingle is marked at intervals with'lines 16 parallel to side 14 of the individual shingles. Substantially the same result may be obtained by overlapping in stepped relation (Fig. 9) a series of individual shingles 1'2, each of which is formed with a convex-like butt end 18 and overlapped in stepped relation with sides 19 arranged to form a continuous unbroken side of the slab. These strips are laid diagonally in overlapping courses, (Fig; 10) with the sides or the butt ends cooperating with the marking on the slab surface for simulating in- ,7 1,928,285 butt end for dividing the surface in simulation of figuration, each having a length equal to at least twice the width, and laid irregularly staggered in courses.

2. A roof composed of slab shingles, each having a symmetrical configuration of the butt with the sides thereof diverging uniformly, each having a length equal to at least twice the width, and laid irregularly staggered in courses.

3. A roof composed of slab shingles, each having a body extending in the form of diverging wings, and having a length equal to at least twice the width, and laid, irregularly staggered in courses.

4. A roof composed of slab shingles, each having a symmetrical unitary configuration of the butt of polygonal downwardly convex-like configuration, each having a length equal to at least twice the width, and laid staggeredly in courses.
